APPARATUS FOR CLARIFYING SUGAR SOLUTIONS.

SPECIFICATION forming part of Letters Patent No. 479,250, dated July 19,1892.

Application filed November I8, 1891. Serial No. 412,321. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE WA'rsoN DEM- ING, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements inProcesses of Clarifying and Filtering Saccharine Solutions; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to an improved apparatus for clarifyingsaccharine solutions; and it has for its general object to clarifysaccharine solutions after proper treatment with reagents and reduce thesame to a condition for rapid and complete filtration.

To the attainment of the foregoing and other objects the inventionconsists in the peculiar construction and relative arrangement of theelements making up my improved apparatus.

In the annexed drawing the figure is a view of my improved apparatus,partly in section and partly in elevation.

Referring by letter to the said drawing, A indicates the heater ordefecator of my improved apparatus, which is preferably of a cylindricalform and is horizontally disposed, as shown. This heater or defecator A,which has its ends closed, as shown, is provided adjacent to said endswith the partitions a, which are connected by the steam-pipe G, asshown. Leading from a suitable source of supply to one of the chambers aformed between the partitions a and the ends of the heater or defecator,is a steam-pipe F, which is designed to conduct the heating agent to theheater, and leading from the other chamber a formed between thepartitions a and the end walls of the heater, is a steam-discharge pipeH, which conducts the steam from said heater. Thus it will be readilyperceived that the steam takes continuously through the heater ordefecator, by reason of which said heater or defecator will be kept atahigh even heat.

B indicates a stand-pipe, which is preferably of a cylindrical form andhas its ends closed, as shown. This stand-pipe B is provided adjacent toits ends with partitions b pipe B is the pipe E, and leading from thechamber 0 of the stand-pipe is a pipe L, which discharges into asuitable filter. (Not illustrated.) In practice the heater or defecatoris heated to a temperature of about 220 Fahrenheit, which will coagulatethe impurities in the solution that would not be affected by a lesstemperature and will render their removal possible. The high heating ofthe solution in the heater or defecator not only serves to clarify thesame by coagulating the impurities, but it serves to reduce the solutionto a thin consistency, whereby the same may be rapidly and thoroughlyfiltered.

By reason of the heated saccharine solution from the heater or defecatorA taking through the pipes K of the stand-pipe B it will be readily seenthat the solution entering the chamber 0 from the feed-pipe C will besuperheated byabsorbing a portion of the heat of the heated solution,whereby it will be rendered thinner and will consequently flow faster.By the solution in the chamber a absorbing a portion of the heat of theheated solution it will be further seen that a portion of the heat issaved in the apparatus and the heated solution is partially cooled, sothat it will not injure the filter or filters employed, which is ahighly-important desideratum.

Having described my invention, what I claim is- The apparatus,substantially as and for the purpose setforth, comprising the heater ordefecator having the chamber a, the chambers a and the pipes connectingthe chambers a the steam-feed pipe connected with one of the chambers othe steam-discharge pipe connected with the other chamber a thestandpipe having, the chamber 0 the chambers c to operate substantiallyas and for the purc, and the pipes connecting said chambers c pose setforth. 1o 0, a pipe connecting the chamber 0 of the In testimony whereofI affix my signature in stand-pipe and the chamber a, of the heaterpresence of two witnesses.
